Andrew Griffiths and iDEFENSE Labs discovered a problem in tcpdump, a
powerful tool for network monitoring and data acquisition. An
attacker is able to send a specially crafted network packet which
causes tcpdump to enter an infinite loop.

In addition to the above problem the tcpdump developers discovered a
potential infinite loop when parsing malformed BGP packets. They also
discovered a buffer overflow that can be exploited with certain
malformed NFS packets.

For the stable distribution (woody) these problems have been
fixed in version 3.6.2-2.3.

The old stable distribution (potato) does not seem to be affected
by these problems.

For the unstable distribution (sid) these problems have been fixed in
version 3.7.1-1.2.
